解决

方式一：安装python解决(正确配置系统环境变量)，python(v2.7 recommended, v3.x.x is not supported) - 推荐
下载：http://www.python.org/ftp/python/2.7.3/python-2.7.3.msi

自行下载
npm install --python=python2.7     #先下载
npm config set python python2.7   #再设置环境

方式二：先用管理员身份打开cmd - 推荐
1.安装 npm install -g node-gyp
2.安装 npm install --global --production windows-build-tools
